**PsyDAG**, Tuesday, January 31, 2012 at 10:35pmLet x = adult tickets and y = student ones.

x = 9 - y

10x + 8y = 78

Substitute 9-y for x in second equation and solve for y. Insert that value into the first equation and solve for x. Check by inserting both values into the second equation.

$78.00 minus the $48.00 = $30.00

$30.00 divided by $10.00 Adult Cost = 3 adult tickets.
